[ft] diff Pixel height

[samaram s]

HI,

I am setting my glyph size as 10,on 72dpi.

I assumed i will be getting a glyph height of 10 pixels,But it is not?

  error = FT_Set_Char_Size( face,10*64,0,72,0 );


I have attached my bitmap glyph i got for arial.ttf file,for letter "a".

Why am i getting glyph of size not equal to 10 pixel height.Can anyone please clarify me?

Thanks
